PLOW.

SPECIFICATION forming part of Letters 'Patent No. 436,389, dated September 16, 1890. Application ned May s, 1890. serial No. 350,476. (No man.)

To all whom it may concern:

Be it known that I, HENRY JACKSON DAvIs, acitizen of the United States, residing at Central Institute, in the county of Elmore and State of Alabama, have invented a new and plows with each other and with the draft-bar,

all in such a manner as to admit of the convenient adjustment and manipulation of the various parts.

With these ends in View my invention consists, essentially, in the improved construction of the handle-clamps, the heel-clamps, and a clamping device for connect-ing the beams with each other and with the draft-bar, all as Will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a perspective viewof a double plow em- Fig. 2 is a side elevation of the same. Fig. 3 is atransvcrse sectional view taken through the beams, handle-clamps, and the lowerends of the handles on line 3 3, Figf2. Fig. 4 is atransverse sectional view taken through the heel-clamps on the line 4 4 of Fig. 2. Fig. 5 is a transverse sectional view taken through the sleeve or clamping device connecting the beams with each other and with the draft-bar on the line 5 5 in Fig. 2. Figs. 6 and 7 are perspective detail views of the right and left hand handle-clamps. Fig. Sis a perspective detail View of the heel-clamp. Fig. 9 is a sectional view taken through the groove or recess of the heelclamp to show the concave bottom of said recess. Fig. 10 is a perspective detail view of the clamping-sleeve connecting the plowbeams and the draft-bar.

Like numerals of reference indicate like parts in all the figures of the drawings.

l 1 designate the plow beams or stocks, which are made of iron, and which are provided with outwardly-bent shoulders or offsets 2. The front ends of said plow beams or stocks are straight and between them is in-1 two separate parts-namely,the clamping-box 5 and the cap 6. The clamping-boxes each consist `of a plate 7, having beveled parallel ends provided with lugs 8, having perforations 9 to receive the clamping-bolts. The sides of said plates are provided with flanges 10, the ends of which are provided with lugs 11. These clamping-boxes, which are in practice applied to the inner sides of the plowbeams, are to be made right and left handed, as will be seen in Figs. 6 and 7 of the drawings, and the angle at which they are mounted with relation to the plow-beams will be determined by the degree of the bevel at the ends of said clamping-boxes. The lugs 11 of the iianges 10 of said boxes are adapted to fit against the upper and lower edges of the plow-beams, and the clamping-boxes, as I term them, are to be made of suitable size to receive the lower ends of the handles.

The caps 6 of the clamping-boxes consist simply of plates having beveled ends to correspond with the beveled ends of the boxes, said plates being also provided at their ends with perforated lugs 12 for the passage of the clamping-bolts. The edges of the said capplates are also provided at their ends with lugs 13 to engage the upper and lower edges of the plow-beams.

14C 14 designate the handles, which are of ordinary construction, and the lower ends of which are inserted into the clamping-boxes between the latter and the plow-beams. Said handles are provided at their lower ends with transverse perforations 15 for the passage of .the clamping-bolts 1G and 17.

The lower clamping-bolts 16 extend through the clamping-boxes, the cap-plates, and the handles, and are provided with nuts, which may be tightened to secure the parts together.

The upper clamping-bolt 17 consists of a rod, screw-threaded at both ends, so .as to eX- tend through both of the clamping-boxes, handles, and cap-plates, nuts 18 being provided to be ltightened up against the inner sides of the clamping-boxes and the outer IOO sides of the cap-plates. ln this manner it will be seen that the bolt 17 serves the additional purpose of a brace for connecting the rear ends of the two plow-beams. I would have it understood, however, that this brace may be dispensed with and ordinary bolts substituted therefor when desired.

The operation of this part of my invention will be readily understood. It will be seen that by means of these clamping devices the handles may be attached to the beams very securely and quickly and in such a manner as to admit of any desired adjustment. 1t will further be observed that the plow-beam is not weakened by making perforations therein for the attachment of the handles. Furthermore, when this method of attaching` the handles is adopted there will be no hecessity for connecting the handles by means of rungs orbraces, and the cost of manufacture is consequently lessened, while the handles are not weakened by making perforations therein for the 'reception of such connecting devices. These handle-clamps, as will be readily understood, are not only applicable to the form of plow herein shown and described, but may be used with equally satisfactory results upon all farming implements that require to have handles attached thereto. 'It will also be understood that the shape of the handle-clamps and the bevel at the ends of thesame may be modified according to the use to which they are to be put and the angle at which it shall be desired to secure the handles to the beams.

The handle-clamps are manufactured, preferably, of cast iron, and may be produced at a small expense.

The heel-clamp consists of a block approximately cubical in shape and provided with a narrow longitudinal groove or recess of a Width to iit the width of the plow-beam to which it is applied, and having a curved bottom to correspond with the curve of the standard. The block is designated by 19, the recess by 20, and the curved bottom of said recess by 21. Extending laterally from the recess 20 is a supplemental recess 22, from t-he bottom of which the perforation 23 extends through the block to admit of the-passage of the square shank of a clamping-bolt 24. The upper edge of the block 19 is provided with lugs or flanges 25 to form a seat for the upper edge of the blade or shovel 26. The latter is provided with a suitable perforation 27 for the passage of the clamping-bolt.

In operation the heelclamp is mounted upon the curved standard of the plow-beam, as will be seen in Fig. 1 of the drawings. The clamping-bolt is then passed through the blade or shovel and through the recess 22 and perforation 23 of the clamping-block. A suitable nut is then mounted upon the bolt and tightened, thus securing the shovel and the heel-clamp firmly in position upon the stock or standard. The upper edge of the blade or shovel will rest against the lugs or flanges 25 of the clamping device,fand the said shovel will thus be prevented from turning or working loose upon the bolt. It will be seen that by this means of securing the blade or shovel in position it may be readily adjusted to any desired position, and it will also be noticed that all necessity for weakening the plowstandard by perforating the same for the passage of bolts or similar securing devices 1s avoided. The bottom of the recess 2O is curved to correspond with the curve of the standard, and it may consequently be easily slid to any desired position upon the latter.

2S designates the clamping-sleeve, by means of which the front ends of the plow-beams are connected'with each other and with the,

rack-bar. The said clamping-sleeve is made, preferably, of cast-iron, square in cross-section to receive the front ends of the plow-beams and the interposed draft-bar. The sleeve 28 is provided on one side with a laterally-extending bushing or box 29, which has a screwthreaded perforation 30 to receive the clamping-screw 31, by tightening which latter `the parts are firmly connected. The sleeve 2.8 may, when desired, be provided with longitudinal slots 32 in its upper and lower sides. These slots, when the draft-bar is not used, may be utilized for the reception of an addition plow-carrying standard, as willbe readily understood.

1t will be seen that by this manner of connecting the plow-beams with the draft-bar the latter may be adjusted longitudinally to any desired extent. In like manner either of the plow-beams may be adjusted in advance of the other, which is very frequently desirable. It is obvious that when such longitudinal adjustment of either plow-beam is made the handle-clamp upon said plow-beam must be temporarily loosened to admit of the plowbeam being moved in either direction.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. The construction is exceedingly simple and of such a nature as to, render all the parts of the device exceedingly strong and capable of resisting any strain or Wear to which they may be subjected. It is also obvious that the several parts of the device may be used independently of each other and in other relations than those herein described.

I desire it to be understood that while I have in the foregoing described what I consider to be the simplest and most desirable construction of all the parts of my invention, I reserve the right to make any such changes IIO and modifications as may be resorted to with* out departing from the spirit of my invention.

Having thus described my invention, l claim and desire to secure by Letters Patent of the United States-H 1.
